This piece of music best represents, to me, that states of mind that are experienced in mixed depression-anxiety states, where one oscilates between tension, bleakness, and occasional glimpses of hope for the future. Yet, overall, the affect is rather dreary and detached, which is mimetic of the state of Dissociation seen in panic disorder and other severe anxiety disorders.
Yet, there is undoubtedly a redeeming quality towards the end, as the song pushes through the anhedonic fog from the beginning (as seen by the increasing richness of the harmonic palette) and resolves to a state of ambiguous hope. Enjoy!
